2018-06-28T07:32:12.528086Z 0 [ERROR] Aborting

解决：

pxc节点加入集群，集群的地址不对或者pxc节点通信的端口不对
Failed to open channel ‘pxc‘ at ‘gcomm://192.168.1.210:6600,192.168.1.210:6602‘: -110 (Connection timed out)
提示我无法加入pxc这个集群，查看my.cnf配置文件更改wsrep_cluster_address=‘gcomm://192.168.1.210:6630,192.168.1.210:6632‘
这个集群的地址要填pxc节点相互通信的地址，不能填mysql的服务地址，默认的地址是监听的地址是4567

报错二：

如何解决Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘
先要卸载Linux自带的mysql，删除相关的文件

rpm-qa | grep mysql （注意大小写，如果mysql不行就换MySQL）
yum -y remove mysql的包名
卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除，如果确定没用后就手工删除

rm -f /etc/my.cnf
rm -rf /var/lib/mysql
安装Xtrabackup

rpm -ivh percona-xtrabackup-24-2.4.3-1.el7.x86_64.rpm
可能会出现下面错误提示信息：

Failed dependencies:
libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.3-1.el7.x86_64
perl(DBD::mysql) is needed by percona-xtrabackup-24-2.4.3-1.el7.x86_64

（1）解决 perl(DBD::mysql) ：

yum install -y perl-DBD-MySQL
（2）解决 libev.so.4()(64bit)
可以自行去rpmfind.net搜索系统所需要的rpm包进行下载安装

wget ftp://rpmfind.net/linux/dag/redhat/el6/en/x86_64/dag/RPMS/libev-4.15-1.el6.rf.x86_64.rpm
OK，安装完成
使用Xtrabackup备份

innobackupex --user=root --password=Pengyuanzhi --socket=/var/lib/mysql/mysql.sock /root
（1）Can‘t locate Digest/MD5.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at - line 693.
.pm实际上是Perl的包，只需安装如下软件包即可：

yum -y install perl-Digest-MD5

报错三：

[ERROR] Can‘t start server: Bind on TCP/IP port: Address already in use
[ERROR] Do you already have another mysqld server running on port: 3306 ?

解决：

查看3306端口是否被占用，查看my.cnf配置文件中
wsrep_sst_receive_address=192.168.1.210:6622
wsrep_provider_options = "gmcast.listen_addr=tcp://192.168.1.210:6632;ist.recv_addr=192.168.1.210:6633;"
都不能和mysql服务端口冲突
